Using the 'let' Function for Chaining Multiple Operations

The 'let' function in Kotlin can be particularly useful for chaining multiple operations on an object while maintaining null safety. By using 'let', you can perform several transformations or actions on the object, avoiding the need for explicit null checks and making your code cleaner and more readable.

val user: User? = getUser()

user?.let { 
    // Transform user data
    val userName = it.name.toUpperCase()
    val userEmail = it.email.lowercase()

    // Log user information
    println("User Name: $userName")
    println("User Email: $userEmail")
}
